Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a fire power adjustment device for gas appliance taps.

Conventional structure and its problems As shown in Figure 1, the conventional fire power adjustment device installed on a gas stove, for example, is installed either on one side of the stove or on both the left and right stoves. Separate fire power adjustment devices were made for the left and right sides, and a control lever 1 was installed between the knobs 3 and 3, as shown in Figure 2. The reason why the control lever 1 is provided between the knobs 3 and 3 even if separate left and right heat adjustment devices are made is that in the case of a gas stove with a grill as shown in Figures 1 and 2, the operation lever is located on the grill door 2 side. This is because if the lever 1 is provided, the grill door 2 will become quite hot while the grill is in use, and there is a risk of getting burned when operating the operating lever 1 for adjusting the heat power.

Conventionally, in order to manufacture separate right and left fire power adjustment devices, the entire gas appliance tap main body 4 of the fire power adjustment device shown in Fig. 3 was used.
Two types (one for the left Kotsuku and one for the right Kotsuku) were manufactured. As a result, two die-casting molds are required, and the other large parts that make up the firepower adjustment device are different from each other, resulting in high management costs and high mold investment costs.

Purpose of the Invention The present invention provides a fire power adjustment device that allows a gas appliance tap to be shared, and allows a loosely fitted operating lever to be operated outside the appliance from both the right and left sides of the gas appliance tap when the gas appliance tap is attached to the appliance. provide.

Structure of the Invention In order to achieve the above-mentioned object, the thermal power adjustment device of the present invention controls a gas appliance tap main body for adjusting thermal power through which fuel gas flows, and a gas passage of the gas appliance tap main body to adjust the thermal power, and a needle that is slidably protruded from the gas appliance tap body to the outside in an airtight manner, a pin that is fixed to the protrusion of the needle and transmits the driving force for sliding the needle, and an operating lever that is applied via the pin. In order to operate the needle in the axial direction, the gas appliance plug has a guide groove that slides and guides a pin that rotates with respect to the center axis of the needle, and a rotation shaft hole plate that loosely fits the operating lever. A gas appliance stopper is constructed from a base plate that is fixed to the main body, and the operating lever is operated from outside the appliance by being installed inside the gas appliance, and the needle is slid through a pin in the same manner as the operating lever, A rotary lever that fits loosely into the fitting part of the operating lever and fits inside the appliance, and another operating lever that is joined to the rotating lever and applies the driving force for the sliding movement, In order to accommodate design constraints and facilitate operation of the operating lever outside the appliance, the operating lever may be loosely fitted on either side of the gas appliance tap from the protruding side of the needle and the opposite side thereof. This configuration is characterized by the ability to adjust the firepower of the appliance.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

Fig. 3 is an external view of the heat power adjustment knob for the left stove, and Fig. 4 is an external view of the heat power adjustment knob for the right stove. Fifth
The figure shows a base plate 7 attached to the gas appliance plug main body 4. In FIGS. 3 and 4, a gas appliance plug main body 4 made by die casting has a fire power adjustment part 5 molded at the same time. After turning the knob 3 to open the gas passage, the amount of gas can be adjusted by operating the control lever 1 or 1'. This operating lever is loosely fitted into either of the rotary shaft hole plates 7a and 7b provided on the base plate 7, depending on whether it is for the right stove or the left stove. By operating the operating lever 1 or 1', a pin 9 held by the operating lever at one end and fixed to the needle 6 at the other end slides in a guide groove 7c provided in the base plate 7. This causes the needle 6 to slide and adjust the gas amount. The gas amount adjustment is shown in FIG. 6 when the gas amount is fully opened, and FIG. 7 shows when the gas amount is most restricted.

In FIG. 6, gas entering through the gas closure hole 12 flows through the gap formed between the gas passage molded in the gas appliance plug body 4 and the needle 6, and reaches the gas outlet 4b. In Fig. 7, the operating lever 1
and 1' to reduce the gas amount the most. At this time, the gas entering from the gas closure hole 12 flows through the gas passage molded in the gas appliance plug body 4, but since the needle 6 is in close contact with the wall 4a of the gas appliance plug body, the minimum The gas flows only through the hole 14, where the thermal power is adjusted and reaches the gas outlet 4b. Gas leakage to the outside is stopped by an O-ring 13 provided on the needle 6 portion. The amount of gas between fully open and at its minimum is regulated by the amount of inflow and outflow of the needle. In this embodiment, the main firepower adjustment parts described above are integrated (shared) into a left pot and a right pot, and only the main body of the appliance plug is produced in advance. After that, if it is the left side of FIG. 3, the rotation shaft hole plate 7 of the base plate 7
This is completed by attaching the operating lever 1 to b.

In the case of the right-hand side in Fig. 4, after the L-shaped operating lever 1' and the rotating lever 11 are crimped and integrated,
This is completed by attaching the operating lever 1' to the rotating shaft hole plate A7a of the base plate 7, and attaching the rotating lever 11 to the rotating shaft hole plate B7b.

When turning off the gas, by turning the knob 3 in the stop direction, the return cam 1 fixed to the knob
When the needle 0 rotates to move the operating lever 1 and the rotary lever 11 and stop, the needle 6 is always located at the position shown in FIG.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) There is only one type of mold for the Kotsuku body, which requires the most investment cost, and when the Kotsuku body (gas appliance tap) is attached to the appliance, the operation lever that is loosely fitted can be inserted from both the right and left sides of the gas appliance tap. can be operated outside the appliance, and the operation lever can be easily operated in accordance with the installation location of the gas appliance tap inside the appliance.

(2) The main body of the gas kettle, which is the most important quality part, can be produced consistently without distinguishing between left and right kettles, ensuring stable quality.

(3) Only the main part of the kettle can be produced in advance, and later produced as a left kottoku and a right kottoku, making it easy to handle the quantity even if there is a device with a fire power adjustment kettle on only one side.
